When will this plague end

I owe the Rosminians a great deal. One of them was good enough to be my spiritual director and he introduced me to a wealth of Catholic Spirituality.But the order has got it really badly wrong. How could they have kept quiet following the death of Fr Kit Cunningham when they knew about his past.There is now a wealth of knowledge about the consequences of sexual abuse. There is also a well documented history of Church cover up. With all that, how did they manage to get it so badly wrong?
